Just bought a new 4K (3,840 x 2,160 pixels) ultra high-definition (UHD) TV but do not have any UHD content to play? The AC Ryan Veolo 4K UHD media player could be the answer.

This Android 4.4-based media player lets you stream and play 4K content from the Internet using its built-in dual-band Wi-Fi and Gigabit wired connection.

Veolo's own user interface caters to movie buffs with a smart jukebox that includes the automatic adding of cover art and synopses for their movie collections. It supports most video formats, including 4K H.264, H.265, MKV and BD-ISO.

Ecovacs Deebot D77

$999 (usual price $1,499)Booth: 5G60

Unlike other robotic vacuum cleaners, the Ecovacs Deebot D77 is able to clean many different types of flooring, including wood, marble, tile and carpet of up to 2cm thick.

Its sensors are able to prevent it from falling down the stairs, as well as avoid obstacles and collisions with furniture.

It comes with a docking station that includes a detachable handheld canister and accessories which you can use to clean walls, ceilings and other surfaces.

The Deebot D77 automatically empties its bin into the canister when it returns to the docking station, which means you will not need to manually empty the cleaner.
